IMPROVEMENT IN BUTTONS.

Be itrknown that I, GEORGE COOKE, of Winchester, county'of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Buttons, applicable to general use, and greatly reducing the cost of the button andsimlar articles attached to cloth or leather, without thread; and `I do hereby. declare that the following is a full andexact description ofmy invention, reference being had to the accompanying drawings, and to the letters'ef reference marked thereon.

The nature of my invention consists in the application of the parts A and B, constructed suhstantially as represented in Fig. I, A and B, to the construction and attachment of studs and'buttons.

Figure I. A is the shank of a stud or button, having a groove out near each end, for the purpose of receiving the washer or heading, B, which (B) is so constructed that simple pressure will contract the orifice o, fastening it within the groove, and superseding the process of riveting D, sectional view, illustrating conditions of pressure employed. v

Figure II exhibits parts united in a button; also the contraction of the orifice o of the washer or heading,

when the latter is reduced to a dat disk.

Figure III. Means of attaching to cloth, leather,'&c. y l

To enable others skilled in the art to make and use my invention, I ,will describe the construction and4 use of the `parts A and B.

The Washer or heading (or button) B, is punched, so as to be left in a conical form, and any instrument which will reduce the part B to a flat disk, ivillecontract the orifice o and confine the part B to the shank A more firmly and reliably and economically than by any ordinary riveting. One washer or heading being either the button itself, or forming a part of the button, the other may be applied after the shank is passed through cloth or leather, or other elastic material, by the use of pincers or forceps, having a flat tongue of metal, I-I, Fig. III, (with a slit or opening, la) to supply a metal surface for one side ofthe part B, while the other receives the pressure from thejaw G, Fig. III. To facilitate the reduction ofthe part B to a regular and suitable form,

thejaw Gin Fig. III has a shallow'v socket, s, to receive the edge of the part B, and prevent its spreadingirregularly during the pressure. The principle is more distinctly shown in P, Fig. I.

Fig. II represents, in a sectional view, ahntton in place, C denoting the cloth, A the shank, B the washers or headings, c c the shell and collet" of a button, B and B the form of tho partB before and after being pressed into position on the shank, with the effect of reducing the orifice o.

What I claim, and desire to secure by Letters Patent, is-

A button or stud, its shank attached 'by means of a, disk formed concave, and subsequently compressed,

substantially as described. 4
